Yes, I thought of Eliza when I made my comment. LLMs in their current state are far more convincing than Eliza, but they still have all the limitations that I described. I have no idea whether LLMs can advance to the point where they don't have those limitations anymore-- that's a whole other discussion. My point was to discuss the limitations they have now.
"The therapist's role is to create a safe space for the client to explore their thoughts and feelings, fostering self-awareness and personal growth"... OK. That's an accurate statement, as far as it goes. But the therapist often has to do *more* than just "create a safe space for the client to explore thoughts and feelings". The therapist has to identify when these thoughts are the product of a cognitive bias, when they're maladaptive, and even (in some cases) to identify when the thoughts are delusional. They also have to do a whole, long list of other stuff, as I'm sure you know.
Your description of Rogerian therapy (I won't call it a *definition* of Rogerian therapy, since you didn't claim that it was a definition) sounds to me like a description of "supportive" therapy. You listen, you make sure the patient feels listened-to, you make sure they feel "safe" and that they don't feel judged, you offer validation as appropriate and mirror the patient's affect when appropriate. But this is a description of *supportive* therapy only, and supportive therapy is a very, very limited and unambitious type of therapy. It's also a potentially *harmful* form of therapy if it is applied indiscriminately to all patients and all situations. "Your supervisor is mean to you, and your last supervisor was very mean to you and the one before that, too. I'm really sorry to hear that. It sounds like you've had a rough time with supervisors". (Or worse, "Of course, you feel frustrated. I think anyone would feel frustrated if the Pope was harassing them on Twitter".)
